glusterd: Volume locks and transaction specific opinfos

2013-10-10T07:56:16+00:00

With this patch we are replacing the existing cluster-wide
lock taken on glusterds across the cluster, with volume locks
which are also taken on glusterds across the cluster, but are
volume specific. So with the volume locks we are able to perform
more than one gluster operation at the same time, as long as the
operations are being performed on different volumes.

We maintain a global list of volume-locks (using a dict for a list)
where the key is the volume name, and which saves the uuid of the
originator glusterd. These locks are held and released per volume
transaction.

In order to acheive multiple gluster operations occuring at the
same time, we also separate opinfos in the op-state-machine, as a
part of this patch. To do so, we generate a unique transaction-id
(uuid) per gluster transaction. An opinfo is then associated with
this transaction id, which is used throughout the transaction. We
maintain a run-time global list(using a dict) of transaction-ids,
and their respective opinfos to achieve this.

protocol/server: Implement barriering mechanisms for fops

2013-10-07T08:21:42+00:00

Barriering allows cbk's responses to be held back until either a
timeout or a un-barrier event is received.

The event is triggered by a brick-op.

barrier-timeout, barrier-queue-lenght, and barrier-fops are currently
exposed as a xlator-options only
